Get Driving -> Adaptive cruise control Guide for Peugeot 308 4 Door Second Genration (2014-2020)

Driving

Principle of operation

Adaptive cruise control

This system is a driving aid that cannot,

in any circumstances, replace the need to

observe speed limits and safety distances,

nor the need for vigilance on the part of

the driver.

Some vehicles present on the road may

not be properly seen or may be poorly

interpreted by the camera and/or radar

(e.g. a lorry), which may lead to a poor

assessment of the distances and lead to

the vehicle inappropriately accelerating or

braking.

The driver must be ready at all times

to retake control of their vehicle by

permanently holding both hands on the

steering wheel and keeping their feet near

the brake and accelerator pedals.

The system automatically adapts the speed of

your vehicle to that of the vehicle in front, to

maintain a constant distance.

If the vehicle in front is driving more slowly, the

system slows, or even stops your vehicle (with

the EAT8 automatic gearbox or the BlueHDi

150 S&S EAT6 engine), using engine braking

and the braking system.

If the vehicle in front accelerates or changes

lane, the cruise control progressively

accelerates your vehicle to return to the

programmed speed.

If the driver operates a direction indicator to

overtake a slower vehicle, the cruise control

allows your vehicle to temporarily approach

the vehicle in front to assist the overtaking

manoeuvre, though never exceeding the

programmed speed.

This system provides the following

functions:

-

Automatically maintains the vehicle

at the speed set by the driver.

Automatic adjustment of the

distance between your vehicle and

the one in front.

-

With the EAT8 automatic gearbox or with the

BlueHDi 150 S&S EAT6 engine, automatic

adjustment can cause your vehicle to come to a

complete stop.

It manages the acceleration and deceleration

of the vehicle by automatically acting on the

engine and the braking system.

Steering mounted control

The brake lamps illuminate as soon as

the braking system is activated with

deceleration of the vehicle.

To do so, it has a radar located in the front

bumper.

Primarily designed for driving on main

roads and motorways, this system only

works on moving vehicles, driving in the

same direction as your vehicle.

can only be reactivated when all of the

safety conditions are met. The "Activation

displayed if reactivation is not possible.

With the engine running and cruise control on

(green), you can modify the speed setting.

As a precaution, it is recommended

that you select a cruise speed close to

the current speed of your vehicle, so

as to avoid any sudden acceleration or

deceleration of the vehicle.

Modiﬁcation from the current

speed

Reactivating the function

F By successive short presses on button 2

or 3, to lower or raise the setting in steps of

1 mph (km/h),

F By a maintained press on button 2 or 3, to

lower or raise the setting in steps of 5 mph

(km/h).

With a manual gearbox

To reactivate the function, the driver must

accelerate to reach at least 19 mph (30 km/h),

then press one of the buttons 2, 3 or 4.

Modification of the programmed

inter-vehicle distance

With the EAT8 gearbox or with the BlueHDi

150 S&S EAT6 engine

Take care: pressing and holding button 2

or 3 results in a rapid change in the speed

of your vehicle.

Following braking of the vehicle bringing it to

a complete stop, the system holds the vehicle

stationary; the cruise control is paused.

The driver should press the accelerator pedal

to move off, then reactivate the system above

19 mph (30 km/h) by pressing button 2, 3 or 4.

If the driver takes no action following this

immobilisation, the electric parking brake is

applied automatically after a while (approx. five

minutes).

Three threshold settings are suggested for the

inter-vehicle distance:

-

"Distant" (3 dashes),

"Normal" (2 dashes),

"Close" (1 dash).

seconds.

F Press button 5 again to save the suggested

The speed displays immediately in the

instrument panel as the new speed setting.

As a safety measure, wait until the current

speed approaches the speed setting to

reactivate the function by pressing button 4.

The change then takes effect.

Driving

This setting remains in memory, whatever the state

of the system and when the ignition is switched off.

The selection also applies to the stopping

distance (with EAT6 and EAT8 automatic

gearbox).

Exceeding the programmed

setting

It is possible to exceed the speed setting

temporarily by depressing the accelerator

pedal.

The cruise control no longer manages the

braking system during this period.

Simply release the accelerator pedal to return

to the programmed speed.

If the programmed speed setting is exceeded,

the display of the speed setting disappears

and a message "Cruise control suspended"

is displayed until the accelerator pedal is

released.

Driving

Following braking of the vehicle bringing it to

a complete stop, the system holds the vehicle

stationary; the cruise control is paused.

The driver should press the accelerator pedal

to move off, then reactivate the system by

pressing button 2, 3 or 4. If the driver takes no

action following this immobilisation, the electric

parking brake is applied automatically after a

while (approx. five minutes).

When the driver must suspend the cruise

control system:

The system must not be activated in the

following situations:

-

When the "space-saver" spare wheel is

being used (depending on version).

When towing.

-

Following an impact on the front bumper.

Be particularly careful:

-

When motorcycles are present and

when there are vehicles staggered

onto the traffic lane.

-

Vehicles in a tight bend.

When approaching a roundabout.

Operating limits

-

When you enter a tunnel or cross a

bridge.

The system cannot exceed the limits of the

laws of physics.

The system cannot deal with certain situations

and the driver has to take back control of the

vehicle.

-

When following a narrow vehicle.

Cases of non-detection by the radar:

Reactivate cruise control when conditions

permit.

-

Pedestrians, some cyclists, animals.

Stationary vehicles (traffic jam, breakdown,

etc.).

Cases where the driver is urged to take

back control immediately:

-

Excessively sharp deceleration of the

vehicle in front of you.

-

Vehicles crossing your lane.

Oncoming vehicles.

-

When a vehicle cuts in sharply between

your vehicle and the one in front.

Driving

Malfunction

The cruise control operates by day and

night, in fog or moderate rainfall.

However, it is strongly recommended that

you always keep a safe distance from

vehicles ahead, according to the driving

conditions, the weather and the road

surface.

Use the cruise control only where the

driving conditions allow running at a

constant speed and keeping an adequate

safety distance.

Do not activate the cruise control in urban

areas where pedestrians are likely to

cross the road, in heavy traffic (except for

versions with EAT8 gearbox), on winding

or steep roads, on slippery or flooded

roads, when there is snowfall, if the front

bumper is damaged or when the brake

lamps have failed.

In certain circumstances, it may not

be possible for the speed setting to be

maintained or even reached: loaded

vehicle, ascending a steep hill, etc.

The system is not intended for the

following situations:

-

the front end of the vehicle has been

modified (addition of long-range

headlamps, painting of the front

bumper),

If the cruise control

malfunctions, dashes are

displayed instead of the

cruise control speed setting.

-

driving on a racing track,

driving on a rolling road,

use of snow chains, non-slip covers or

studded tyres.

If this warning lamp comes

on, accompanied by an alert

message and an audible

signal, this confirms a

malfunction.

The use of mats not approved by

PEUGEOT may interfere with the

operation of the cruise control.

Have the system checked by a PEUGEOT

dealer or a qualified workshop.

To avoid any risk of jamming of the pedals:

-

ensure that the mat is secured

correctly,

never fit one mat on top of another.

The adaptive cruise control deactivates

automatically if the use of a "space-saver"

type spare wheel is detected or if there is

a malfunction on the lateral brake lamps or

trailer brake lamps (for approved trailers).

The following situations may interfere with

the operation of the system or prevent it

from working:

6

-

poor visibility (inadequate street

lighting, falling snow, heavy rain, dense

fog, etc.),

-

dazzle (headlamps of an oncoming

vehicle, low sun, reflections on a damp

road, leaving a tunnel, alternating

shade and light, etc.),

-

camera or radar masked (mud, frost,

snow, condensation, etc.).

In these situations, detection performance

may be reduced.
